Abstract
An intake manifold assembly for an internal combustion engine of a vehicle includes a plenum, a plurality of lower runners coupled to and in fluid communication with the plenum, and a plurality of upper runners. Each of the upper runners is coupled to and in fluid communication with one of the lower runners. The plurality of upper runners includes a single dedicated upper EGR runner configured for supplying combustion air to at least two dedicated EGR cylinders. A primary throttle body is coupled to the plenum and configured for regulating a flow rate of compressed combustion air through the plenum. An EGR throttle body is coupled to the dedicated upper EGR runner and configured for regulating a flow rate of the compressed combustion air through the dedicated upper EGR runner to control the flow rate of the compressed combustion air to the dedicated EGR cylinders.
